Electrochemical determination of ascorbic acid using electrochemically deposited polyaniline

Abstract

Electroconducting polymers are promising materials to be used in various fields including: batteries, capacitors, electronic devices, corrosion, biosensors and sensors[1,6]. Polyaniline is probably the most investigated electroconducting polymer, due to low cost monomer, conductivity, environmental stability. Polyaniline can be obtained by chemical or electrochemical oxidative polymerization of aniline. Electrochemical synthesis is performed in anodic process directly from acidic aqueous electrolyte containing aniline. Polyaniline can be used as electrode material for electrochemical determination of ascorbic acid based on electrocatalytic oxidation of ascorbic acid.
